Moenus
Moenus (the Main), a navigable river of Germany, which has its sources in the Sudeti Montes, near the town of Menosgada, and after flowing in a western direction through the country of the Hermunduri and the Agri Decumates, empties itself into the Rhine, a little above Moguntiacum (Plin. Nat. 9.17; Mela, 3.3.3; Amm. Marc. xvii. I; Tac. Germ. 28; Eumen. Paneg. Constant. 13.)
